TRANSMISSION APPARATUS.

Application filed July 29,

To all whom it may concern.'

Be it known that l, MAX T. VOIGT, a citizen of the United States, and a resident of Reading, county of Berks, and State of Pennsylvania, have invented a certain new and useful Improvement in Transmission Apparatus, of which the following is a specification.

The present invention relates to apparatus for transmitting power from a continuously operating power line shaft to a plurality of mechanisms, such -as sewing machines,` adapted to be operated therefrom, and is particularly applica-ble to use in connection with the type ofapparatus villustrated and described in my Patents No. 1,431,198 of October 10, 1922, and No. 1,444,573 of February 6, 1923, althoughits use is not confined to such devices, but may be employed in connection with other forms of power transmission apparatus. l

The object of the invention is to provide means for alining power transmitting elements independently of the4 supports or other instrumentalities with which they may be associated. A further object is tol provide means whereby in line shafting having a plurality of pivoted bearings each bearing may be secured in alinement with the other bearings.

These and further objects will more fully appear in the following specification and accompanying drawings considered together or separately. f

ln the accompanying drawings, in which like parts in all of the several figures are designated by corresponding characters of reference, is illustrated one embodiment of the invention.

In the drawings Fig. 1 is a side elevation, partly in section, of a transmission apparatus embodying the invention. I

Fig. 2 is an end elevation of the same.

Fig. 3 is a similar view showing a modification, and

Fig. 4 is a longitudinal section of the dev1ce.

ln the embodiment of the invention illustrated 1 designates a standard or pedestal which may be supported in any desired manner and projecting upwardly from the same is a pair of spaced arms 2 and 3, each provided with a threaded perforation in its upper end to receive a conically pointed set 1922. Serial No. 578,296.

screw 4. The screws 4 are in axial alinement. whereby the transmission proper is pivoted to the pedestal 1.

The set screws 4 engage diamctrically opposed conical recesses in an element 5. The element 5 comprises a cylindrical portion in which a power shaft (i has a bearing, and a conically recessed extension 7 in axial alinement therewith, which extension forms the stationary member of a brake, the movable member 8 of which is carried on a pulley 9 which in turn is rotatably mounted on an extension of the element 5.

The pulley 9 carries on its side opposite the brake member 8 a female'clutch member 10 adapted to cooperate with a male clutch member 11 fast to the shaft 6. A shifter 12 pivoted to the pedestal 1, extends through a gap in the extension 7, and a crutch at the upper end thereof engages pins 1S extending diametrically from the hub 17 of the pulley whereby the latter may be moved longitudinally of the shaft to be clutched to the vsame through the member' 11 and be rotated therewith. A. spring 12a bearing against a flange on an extension of the element 5 and against the. pulley 9 will -break the contact between the members 10 and 11, and engage the brake member 8 with the stationary element 5 to arrest the rotation of the pulley when the shifter is released.

The arm 2, in the embodiment of the invention illustrated, is extended upward, and is provided with set screws 13 and 14 one above and one below the set screw 4. Each of the set screws 13 and 14 is threaded in the arm 2 and is provided with a jam nut by means of which the screw may be secured in position. Each set screw 13 and 14 bears against a boss' 415 or 16 on the element 5;

When installing a line shaft, such as 6 composed of a plurality of sections coupled together, the bolts 13 and 14'arc backed away from the bosses 15 and 16 and the shaft, as a whole, is carefully alined without the load thereon.' The fact that the bearing members 5-7 are pivoted, as on the screws 4, will facilitate the alining of the shaft. llVhen the shaft is in proper alinement the bolts 14 and 15 are carefully screwed up each to engage its respective boss 15 or 16. and the jam nuts on the bolts are brought up against the arm 2 or 3 to lock the bolts 12, pull a shaft section out of alinement the same may be brought back to proper position by manipulation of the bolts 13 and 14.

Any number of adjusting set screws 13 may be employed as desired or necessary, and they may be so positioned as to resist the pull of the belt in any direction. In Fig. 3 four adjusting screws are shown, two carried by-the arm 2, and two by the arm 3.

In accordance with the provisions of the patent statutes the vprinciple of the invention has been described, together with the apparatus which is now considered to represent the best embodiment thereof, but it is desired to have it understood that the apparatus shown is merely illustrative, and that the invention may be carried out in other ways.
